Calendar of Upcoming Events

2020 was challenging for everyone. Dave has had the opportunity to present occasional online classes through various companies and organizations. Great progress has been made ensuring adults  are vaccinated against the corona virus, so conferences and in-person seminars are now being scheduled.  We will be posting Dave's schedule here as soon as we have dates and locations, and add specifics as the various society's publish them.  Thank you for your patience.
